Answer:

At 1.5 seconds and 2.5 seconds

Step-by-step explanation:

Because this is parabolic motion, the object will reach the height of 68 feet when it's going up AND when it's coming down. In order to find out those times, you set the h on the left side of the equation equal to 68, because h stands for height.

Set that equal to 0 and factor to solve for t:

Using the quadratic formula, we get t = 1.5 and t = 2.5

Alisiya [41]

Answer:

f(x)=5120(1.25)^{x}

Step-by-step explanation:

As per the given question

As we know that

f(x) and x are related by following equation

f(x)=a( {b})^{x}

where

b is the common ratio

Now first we have to compute the value for b which are as follows

\frac{6400}{5120}= 1.25

\frac{8000}{6400}= 1.25

Like if we take the ratio by this method than it comes 1.25

Therefore the common ratio, b = 1.25

So,

a = 5,120

Hence, the equation which model the relationship between the number of weeks and the number of viewers is

f(x)=5120(1.25)^{x}

Math help will give brainliest what is X and M angle A
Anna [14]
Supplementary = 180 degrees...

A + B = 180

3x + 12 + 7x + 38 = 180

10x + 50 = 180

10 x = 130

x = 13 

To find the A just substitute x in...

 
3 ( 13) + 12  

A = 51

To check substitute the x..

A + B = 180

3(13) + 12 + 7(13) + 38 = 180
        51 + 129 = 180
            180 = 180
